Dutcher, White Bear Lake, Minn., assignor to Whirlpool Corporation, a corporation of Delaware Filed June 1, 1966, Ser. No. 554,464 Claims. (Cl. 285--49) ABSTRACT OF THE DISCLOSURE A mounting apparatus for a food waste disposer which includes fastening apparatus for mounting the sink flange permanently to the sink and fastening apparatus for mounting the disposer grinding chamber to the sink flange. The grinding chamber top portion has a split clamp ring for effecting the installation and removal of the disposer without disturbing the sink flange.

One of the features of this invention is to provide an apparatus for mounting a waste disposer on a sink drain conduit in which the apparatus comprises a resilient member extending around the conduit, mounting means for mounting the resilient member in this position on the conduit, engaging means on the disposer for engaging the resilient member on one side of the conduit, a clamp for engaging the resilient member and the disposer simultaneously on the side of the conduit opposite the engaging means and means for drawing the engaging means and clamp means toward each other with the drain conduit and resilient member therebetween so as to releasably retain the disposer on the conduit.

Other features and advantages of the invention will be apparent from the following description of one embodiment thereof taken in conjunction with the accompanying drawings. 0f the drawings:

FIGURE 1 is a fragmentary sectional view through a portion of a sink drain and the top of a disposer chamber attached thereto.

FIGURE 2 is a plan view of the top of the disposer chamber and the mounting means.

FIGURE 3 is a fragmentary vertical sectional view taken substantially along the line 3-3 of FIGURE 2.

FIGURE 4 is an enlarged detail, fragmentary sectional view of a portion of FIGURE 1.

The waste disposer chamber is mounted on a portion of the sink drain conduit, here shown as the generally cylindrical sink flange 11, which extends downwardly from the bottom 12 of the kitchen sink. At the bottom of the flange 11 there is provided a circular groove 13 that opens outwardly and which serves as a mounting means for mounting a circular resilient member or gasket 14 which may be made of any rubbery material but is preferably neoprene.

The disposer chamber 10 is provided with engaging means here shown as a projecting flange 15 that engages and is embedded in the outer surface portion of the resilient member or gasket 14. As is shown in FIGURE 2, the engaging flange 15 extends about 180 around the circular opening of the top of the disposer chamber 10. Flange 15 is integral with the chamber. In addition, there is provided clamp means 16 that is separate from the disposer chamber 10 but which also extends about 180. As can be seen in FIGURE 3, the engaging means 15 and clamp means 16 are similarly shaped in cross section. The clamp means 16 is provided with an inwardly projecting flange 17 that is shaped similarly to the flange 18 of the engaging means 15. The flange 17 is adapted to be embedded in the outer surface portion of the gasket 14 in the same manner as is the flange 18.

In addition, the clamp means 16 is provided at about its midpoint with a thickened portion 19 having an underice lying inwardly projecting flange 20 that projects under and engages an outwardly extending flange .21 on the top of the disposer chamber 10. In order to hold the clamp means 16 in assembled relationship with the disposer chamber 10, there are provided means shown as oppositely diametrically located bolts 22 for drawing the engaging means and clamp means toward each other with the sink flange 11 and resilient member 14 therebetween. These bolts pass through outwardly projecting ears 23 and 24 on the engaging and clamp means 15 and 1-6.

In order to aid in retaining the assembly in position and to insure continuance of the resilient mounting, a groove 13 With an outwardly projecting ledge portion 25 is formed on the bottom of sink flange 11 and underlies the bottom of the resilient member 14 as shown most clearly in FIGURE 4. As can also be seen from FIGURE 4, the bottom of the gasket 14 is provided with a pair of step portions 26 and 27 with the portion 26 underlying the flanges 17 and 18 and the step portion 27 being spaced outwardly from the portion 26 .and located in a cavity 28 on the bottom of the engaging means 15 and a similar cavity 29 on the bottom of the clamp means 16.

The above described mounting apparatus provides a secure yet resilient mounting for a waste disposer of the type used in the drain immediately beneath a kitchen sink. There are very few parts required and the disposer is very easily secured in place. Thus, with the provision of the sink flange 11 installation of the disposer merely requires that the gasket 14 be positioned in the groove 13, the disposer then lifted up and moved into position with the engaging means 15 in proper relationship with the gasket 14, the clamp means or C-c'lamp 16 then placed in position to engage the gasket 14 and the disposer housing flange 20, as illustrated, and finally the bolts 22 attached to draw the engaging and clamp means 15 and 16 together to complete the assembly.

As can be seen, the disposer is isolated from the sink itself by the vibration absorbing resilient gasket member 14. Furthermore, installation is simplified by permitting supporting the weight of the disposer from the sink flange 11 during installation. In addition, only two fasteners, the bolts 22, are required to provide a secure mounting of the disposer on the bottom of the sink.

Having described my invention as related to the embodiment shown in the accompanying drawings, it is my intention that the invention be not limited by any of the details of description, unless otherwise specified, but rather be construed broadly within its spirit and scope as set out in the accompanying claims.

The embodiment of the invention in which an exclusive property or privilege is claimed is defined as follows:

1. Apparatus for mounting a Waste disposer on a sink drain conduit, comprising: a continuous resilient member extending around said conduit, mounting means for mounting said resilient member on said conduit to extend therearound; arcuate engaging means on said disposer for surrounding and engaging said resilient member on one side of said conduit; arcuate clamp means for engaging said resilient member and said disposer on the opposite side of said conduit; and means for drawing said engaging means and clamp means radially toward each other with said drain conduit and resilient member therebetween.

2. The apparatus of claim 1 wherein said engaging and clamp means are each provided with an inwardly projecting flange engaging said resilient member.

3. The apparatus of claim 2 wherein said mounting means comprises a groove having a bottom ledge underlying the bottom of said resilient member, both said resilient member and said groove are circular, the groove opens outwardly, and said engaging and clamp means References Cited contact said resilient member outwardly of said grooveQ UNITED STATES PATENTS 4.
